Currently by running the following test:
=> setenv bootcmd reset
=> save
=> reset
, we observe a hang after approximately 20-30 minutes of stress reboot test.
Investigation of this issue revealed that when a single DDR chip select is used,
the hang does not happen. It only happens when the two chip selects are active.
MX53 reference manual states at "28.6.2 Memory ZQ calibration sequence":
"The controller must keep the memory lines quiet (except for CK) for the ZQ
calibration time as defined in the Jedec (512 cycles for ZQCL after reset, 256
for other ZQCL and 64 for ZQCS)."
According to the SDE_0 and SDE_1 bit descriptions from register ESDCTL_ESDCTL:
"Writing 1 to SDE0 or SDE1 will initiate power up delays as JEDEC defines.
Power up delays are a function of the configured memory type (DDR2/DDR3/LPDDR2)"
So make sure to activate one chip select at time (CS0 first and then CS1 later),
so that the required JEDEC delay is respected for each chip select.
With this change applied the board has gone through three days of reboot stress
test without any hang.

When booting in JTAG mode, there is no way to use soft break-points, and
no way of knowing when SPL has finished executing (so the user can issue
a 'halt' command to load u-boot.bin for example)
Add a debug output and simple loop to stop execution at the completion of
the SPL initialisation as a pseudo break-point when booting in JTAG mode

Section 4.1.2 of Freescale Application Note AN4199 describes the
configuration required to operate the mx28 from a 5V source without a
battery.
This patch changes the behaviour of the dropout control of the DC-DC
converter (refer to section 11.12.9 of the mx28 Application Processor
Reference Manual - Document Number: MCIMX28RM, Rev 2, 08/2013) to the
following:
- Always use 4P2 Linear Regulator if CONFIG_SYS_MXS_VDD5V_ONLY is defined
- Switch between 4P2 Linear Regulator and Battery, using whichever has
the highest voltage if CONFIG_SYS_MXS_VDD5V_ONLY isnot set (this is
the same as the pre-patch behaviour)

It is difficult to track down fail to boot issues in the mxs SPL.
Implement the following to make it easier:
- Add debug outputs to allow tracing of SPL progress in order to track
where failure to boot occurs. DEUBUG and CONFIG_SPL_SERIAL_SUPPORT must
be defined to enable debug output in SPL
- Add TODO comments where it is not clear if the code is doing what it
is meant to be doing, even tough the board boots properly (these comments
refer to existing code, not to any code added by this patch)

Move board/compulab/common/splash.c code to
common/splash_source.c to make it available for everybody. This move
renames cl_splash_screen_prepare() to splash_source_load(), and
the compilation of this code is conditional on CONFIG_SPLASH_SOURCE.
splash_source features:
* Provide a standardized way for declaring board specific splash screen
locations
* Provide existing routines for auto loading the splash image from the
locations as declared by the board
* Introduce the "splashsource" environment variable, which makes it
possible to select the splash image source.
cm-t35 and cm-fx6 are updated to use the modified version.

- introduce struct splash_location
- introduce enum splash_storage
- update cl_splash_screen_prepare() to take an array of above struct

This patch adds the new Barco platinum platform. It currently
includes those two boards:
platinum-titanium
-----------------
This is the same board as the titanium that is already supported in
mainline U-Boot. But its now moved to this new platform to support
multiple "flavors" of imx6 boards in one directory. Its also moved
to support SPL booting. And with this we use the run-time DDR
configuration of this SPL support. The board is equipped with the
Micron MT41J128M16JT-125 DDR chips. We now can remove the DDR
related registers tuples from the imximage.cfg file. As all this
is done in the SPL at run-time.
platinum-picon
--------------
This board is new and based on the MX6DL with 1GiB DDR using the
Micron MT41K256M16HA DDR3 chips. Its also equipped with 2 NAND
chips (each 512MiB).
